Correct Answer: Vena Cava

Solution : The correct option is Vena cava.

The vena cava is a large vein that returns deoxygenated blood to the heart from various areas of the body. The superior vena cava, which returns blood from the upper body, and the inferior vena cava, which returns blood from the lower body, are the two primary types. These veins are essential for blood circulation throughout the cardiovascular system.
